Please consider RedBear BLE Nano V2 as an alternative.
BLE Nano is the smallest Bluetooth 4.1 Low Energy (BLE) development board in the market. The core is Nordic nRF51822 (an ARM Cortex-M0 SoC plus BLE capability) running at 16MHz with ultra low power consumption.
Developing a Bluetooth Smart enabled 'appcessory' (accessory device + companion application) is easier than ever. You can quickly produce protypes and demos target for Internet of Things (IoT) and other interesting projects. BLE Nano could operate under 1.8V to 3.3V, therefore it works with a lot of electronic components.
Smallest BLE development board, only 18.5mm x 21.0mm
Nordic nRF51822 SoC supports both BLE Central and BLE Peripheral roles
Ultra low power consumption
Support voltage from 1.8V to 3.3V
Software development using mbed.org, GCC, Keil or Arduino
Lots of libraries and examples available
Easy firmware deployment with our MK20 USB board
Work with our free Android App and iOS App
This is without MK20 USB board version, if you need it, please visit BLE Nano with MK20 USB board.

There are three options to program your BLE Nano with MK20 USB Board.
Nordic nRF51822 BLE SDK
If you want the full power of nRF51822, you should use Nordic nRF51822 BLE SDK, we provide a product key for all registered users* of our BLE Nano to download the SDK.
We have prepared a guide "Firmware Development with nRF51822 SDK" to show you how to use the SDK with ARM GCC.
mbed's Bluetooth Low Energy API
The mbed platform, developed by ARM, provides free software libraries and online tools for professional rapid prototyping of products based on ARM microcontrollers. Their Bluetooth Low Energy Development Team has released the mbed BLE API together with some samples. Our "Getting Started with nRF51822" guide shows you how to start programming with mbed.
Arduino Library for nRF51822
We have developed an Arduino library for nRF51822 which will be open-sourced and publicly available in the future; it is still at pre-release stage but we invite all interested registered users* of our BLE Nano to access the pre-release library. Please refer to our "Getting Started with nRF51822" guide for more details.
* You will find a product registration card inside the BLE Nano box with the instruction on how to register.
